The brand-new curing agents from Handai Chemical: HDH6320 and HDH6321 make their dazzling debuts

在涂料、胶粘剂等众多工业应用领域，固化剂作为关键成分，直接决定了产品最终性能的优劣。瀚岱化学一直秉持创新精神，致力于研发高性能材料，如今全新推出两款极具特色的固化剂 ——HDH6320 和 HDH6321，为行业带来全新解决方案。

In numerous industrial application fields such as coatings and adhesives, curing agents, as key components, directly determine the quality of the final performance of products. Handai Chemical has always adhered to the spirit of innovation and been committed to researching and developing high-performance materials. Now, it has newly launched two curing agents with distinctive features - HDH6320 and HDH6321, bringing brand-new solutions to the industry.

一、共有的卓越特性：高光稳定性

I. Common Outstanding Feature: High Gloss Stability

无论您身处何种复杂的工艺环境，HDH6320 和 HDH6321 都能展现出令人惊叹的高光稳定性。在高温固化过程中，它们能够有效抵抗黄变，确保涂层始终保持亮丽色泽，为您的产品披上一层持久闪耀的 “外衣”。

No matter what complex process environment you are in, both HDH6320 and HDH6321 can demonstrate amazing high gloss stability. During the high-temperature curing process, they can effectively resist yellowing and ensure that the coating always maintains a bright color, putting a durable and shiny "coat" on your products.

从汽车涂装生产线，到高端家具的表面处理工序，面对长时间的光照、高温烘烤以及复杂的化学环境考验，这两款固化剂都能坚守阵地，让产品表面的光泽度经久不衰。即便是在户外长期暴露的情况下，如建筑外墙涂料、户外设施防护涂层，使用了它们的产品也能最大限度地延缓光泽度降低，为您的品牌形象加分不少。

From automobile painting production lines to the surface treatment processes of high-end furniture, in the face of tests such as long-term light exposure, high-temperature baking, and complex chemical environments, these two curing agents can hold their ground and keep the glossiness of the product surface durable. Even in the case of long-term outdoor exposure, such as exterior wall coatings of buildings and protective coatings for outdoor facilities, products using them can also maximize the delay of gloss reduction and add a lot of points to your brand image.

二、HDH6321：独具优势，领航应用前沿

II. HDH6321: With Unique Advantages, Leading the Application Frontier

（一）无溶剂配方，绿色环保新标杆

(I) Solvent-free Formula, a New Benchmark for Green and Environmental Protection

在环保要求日益严苛的今天，HDH6321 以其无溶剂特性脱颖而出。传统固化剂中的溶剂成分不仅会挥发造成空气污染，还可能在使用过程中带来易燃易爆等安全隐患。而 HDH6321 完全摒弃了溶剂，既减少了有害气体排放，助力企业轻松满足环保法规要求，又为操作人员营造了更安全、更健康的工作环境，是您迈向绿色生产的理想之选。

In today's increasingly stringent environmental protection requirements, HDH6321 stands out with its solvent-free characteristics. The solvent components in traditional curing agents will not only volatilize and cause air pollution but may also bring safety hazards such as flammability and explosiveness during the use process. However, HDH6321 completely abandons solvents, which not only reduces the emission of harmful gases and helps enterprises easily meet the requirements of environmental protection regulations but also creates a safer and healthier working environment for operators. It is an ideal choice for you to move towards green production.

（二）胺当量更低，成本效益双丰收

(II) Lower Amine Equivalent, Achieving Both Cost and Benefit

成本控制是企业运营永恒的话题，HDH6321 深谙此道。凭借其较低的胺当量，在同等固化效果要求下，您只需使用更少的用量就能达到预期目标。这意味着原材料成本的显著降低，为您的产品在市场竞争中赢得更大的价格优势。同时，更少的用量也减少了后续处理环节，进一步节约了时间和人力成本，让您的生产流程更加精简高效。

Cost control is an eternal topic in enterprise operation, and HDH6321 is well aware of this. With its lower amine equivalent, under the requirement of the same curing effect, you only need to use a smaller amount to achieve the expected goal. This means a significant reduction in raw material costs, winning a greater price advantage for your products in the market competition. Meanwhile, the smaller amount also reduces the subsequent processing steps, further saving time and labor costs and making your production process more streamlined and efficient.

（三）低温干燥性能卓越，突破环境限制

(III) Excellent Low-temperature Drying Performance, Breaking Through Environmental Constraints

面对寒冷季节或低温作业环境，许多固化剂的干燥速度会大打折扣，严重影响生产效率。HDH6321 却能打破这一困境，它具备出色的低温干燥性，即使在温度较低的车间、仓库或是户外冬季施工场景下，依然能够快速干燥固化。这不仅缩短了产品的生产周期，加快了交付速度，还为您拓展了更广阔的施工时间与空间范围，确保项目按时、高质量完成。

In the face of cold seasons or low-temperature working environments, the drying speed of many curing agents will be greatly reduced, seriously affecting production efficiency. However, HDH6321 can break through this dilemma. It has excellent low-temperature drying properties. Even in workshops, warehouses with relatively low temperatures or outdoor winter construction scenarios, it can still dry and cure quickly. This not only shortens the production cycle of products and speeds up the delivery but also expands a broader range of construction time and space for you, ensuring that projects are completed on time and with high quality.

三、HDH6320：精准适配，满足多元需求

III. HDH6320: Precise Adaptation to Meet Diversified Needs

HDH6320 虽然在无溶剂、胺当量和低温干燥性方面不及 HDH6321，但它同样有着自身独特的优势，能精准适配特定的工艺需求。它在具有极佳的兼容性，能够与各类环氧树脂紧密结合，形成均匀、稳定的交联结构，从而为产品赋予卓越的机械性能，如高强度、高韧性等。在一些对硬度、耐磨性要求极高的工业地板涂料、机械防护涂层应用中，HDH6320 凭借其出色的适配能力，助力产品在严苛环境下长期稳定运行。

Although HDH6320 is inferior to HDH6321 in terms of solvent-free, amine equivalent, and low-temperature drying properties, it also has its own unique advantages and can precisely adapt to specific process requirements. It has excellent compatibility and can be closely combined with various epoxy resins to form a uniform and stable cross-linked structure, thus endowing products with excellent mechanical properties, such as high strength and high toughness. In some applications of industrial floor coatings and mechanical protective coatings that have extremely high requirements for hardness and wear resistance, HDH6320, relying on its excellent adaptability, helps products operate stably for a long time in harsh environments.

无论是追求极致环保与成本优化的 HDH6321，还是专注于环氧树脂体系高性能适配的 HDH6320，瀚岱化学的这两款固化剂都为您提供了丰富多样的选择。我们相信，它们必将成为您提升产品竞争力、推动技术创新的得力助手，开启您在工业材料应用领域的全新篇章。

Whether it is HDH6321 that pursues extreme environmental protection and cost optimization or HDH6320 that focuses on high-performance adaptation of resin systems, these two curing agents of Handai Chemical provide you with rich and diverse choices. We believe that they will surely become powerful assistants for you to enhance product competitiveness and promote technological innovation, opening a new chapter in the field of industrial material application.
